Well, there is a thread for maths/science and one for psychology, so there is no reason why bio shouldn't have one!

Use thing thread to discuss biology related topics and ask questions you have about whatever (and hopefully somebody can provide an answer).


I am currently doing biology in college and absolutely loving it. I really want to go onto uni and follow a career in ecology or something of that nature, perhaps even marine biology or something.

Surely Biology is a science?


Someone didn't bother reading the posts above them.

On a friendlier note, I always regretted not doing Biology as a high school subject, perhaps I'll learn some useful stuff in this thread

Well there ya go.


I was wondering, I dont remember which movie, but there was this one dialogue where the guy goes
"Waddaya mean Asian? Indians are technically Asian"

Ive been wondering since then
Do you guys primarily think of Japan/China when you think of Asians or do Indians fall into the mix as well?

Whenever I think 'Asian' I split it up in two parts; Oriental and everything else

But we digress...

So how about those living organisms/anyone want to give me a kick start in basic Biology?


What are you interested in?

For Zoology and botany:
Everything David Attenborough has done. (Check out what happens at around 1:50) ... for example, 'Life', 'Blue Planet' and other awesome BBC documentaries...

If there's one thing that doing Biomed at uni for three years has taught me, is that poking rabbits with needles is generally frowned upon. It has become forbidden fruit that may lead to me hunting wild rabbits with a syringe.



I think I'll enjoy this thread. I may have some questions of my own in the future.

Anyone have any feasible ideas on how to improve the design of the upper limb? So far my ideas includeensuring the scaphoid has blood supply at both proximal and distal ends to prevent avascular necrosis, and perhaps having the ulnar nerve anterior to the medial epicondyle of the humerus to prevent the tingling feeling when you hit your elbow. Beyond that I don't have any real ideas.

Lesson 1 Basic Biology - Watch David Attenborough Documentaries.

Excellent, we can create an informed database full of wonderful lessons that provide a thorough run through of Biology.

Maybe.

Being precariously close to finishing school I hope to continue learning in the year I spend working, do not fail me Bio thread!

I\m majoring in Bio at the local university. Thinking about doing some sort of conservation work. Though I'm taking ecology right now..and the class is fairly boring

Improve how? If its strength alone cut it off and put in a prosthetic like the cheetah blades for the legs. artificals are becoming better than originals

I'm not such a big fan of ecology either...nor zoology and botany

It's not 'cellular' enough

I'm currently doing vetmed, so I may be needing you biochem graduates for a while.

Right, so how do enzymes catalyse reactions, preferably an answer from people who know a bit more than school biology. Currently thinking about writing the essay so that I do a paragraph outlining the mechanisms the different categories use to stabilise the transition state, but if anyone has some points and a source, I will be happy to help in any way I cna for other problems that come up.

I'm going to assume you know about specificity (induced fit, lock and key), enzyme thermodynamics and inhibition so I won't waste our time there, since that's basic biology,and if you're on vetmed, you should know basic biology.

I'm also only going to give you headings, to do your own research, so I'm not only teaching you, you're teaching yourself, a useful tool for university. Look into:

Transition state stabilisation:

through substrate straining
without substrate straining (opposite charge creation)

Alternate pathways
Orientation
Temperature increase

Furthermore:

Enzyme control
Coenzymes and Cofactors
Protein dynamics
Allosteric modulation
Kinetics

I hated that enzyme assignment.

Exactly what I was looking for. Thank you very much. As it stands. I don't understand most of the textbooks, so trying to pick information out is a pain when I don't quite know what I'm looking for.

As I stand, I know it appears to be based around the stabilisation of the transition state (via mechanisms which I will explain in my essay) so lowering the kinetic barrier to a reaction.

For first year and some second year stuff, for all biology based subjects, I highly recommend Biology International Version by Campbell and Reece. Has practically a bit of everything from cellular biology to ecology.


For this year, I am studying anatomy, physiology, homeostasis and biochem. There isn't a massive amount of general biology.

The wikipedia pages on enzymes (and all the terms Deleriumbassist mentioned) are pretty good... even though you can't really use wiki as a credible source


Then don't use wiki. Use wiki's references

Most of my course was made up of biochem and homeostasis. It's a damn good book for those, and you should easily be able to sell it on.

Basically the slant I'm going with in my essay is how to make the upper limb better at its function which I said was mainly manoeuvre the hand freely so it can act as a mechanical manipulator and sensory tool as effectively as possible, while also focussing on points prone to injury and whether there is something intrinsic in the design of the upper limb which makes these points more likely to become injured.

For the HOM course I like the Boron & Boulpaep Medical Physiology book, got plenty of extra details for essays in there too.

I've been wondering this for some time...

What does it mean to 'die of old age'? What is it that kills us? I know that our bodies become more vulnerable to disease and become more fragile, but why?

On a cellular level, what happens to us as we get older. And when does this start to happen? The day we become a fertilized egg?
